Subject: [PATCH 26/28] target/ppc: Use cpu_*_mmuidx_ra instead of MMU_MODE*_SUFFIX
Date: Wed, 11 Dec 2019 20:00:37 -0800 [thread overview]
Message-ID: <20191212040039.26546-27-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191212040039.26546-1-richard.henderson@linaro.org>
There are only two uses. Within dcbz_common, the local variable
mmu_idx already contains the epid computation, and we can avoid
repeating it for the store. Within helper_icbiep, the usage is
trivially expanded using PPC_TLB_EPID_LOAD.
